Shown in Figure 1, the present embodiment relate to a kind of blower fan system.This blower fan system includes travelling blower fan, travelling draught fan automatic control device.
Above-mentioned travelling draught fan automatic control device includes controller 10, three-phase protective switch 20, three-phase ac contactor 30, limit switch 40 and timing piece.
Controller 10 uses programmable logic controller (PLC) (PLC).The programmable controller PLC that the present embodiment relates to is the core of this travelling draught fan automatic control device, and programmable controller PLC has following characteristics: 1) reliability is high, and capacity of resisting disturbance is strong.2) highly versatile, control program variable, easy to use, PLC may utilize various hardware unit to form various control system, user need not control oneself and redesigns and make hardware unit, user is after hardware is be sure of, in the case of the technological process of production changes or produces renewal of the equipment, it is not necessary to change the hardware device of PLC in amount, a change program just can meet requirement.3) function is strong, and wide accommodation both can control a manufacturing machine, a production line, and can control again whole production process.4) program simple, easy-to-use easy to learn.5) system designs, debugs and easy to maintenance, can facilitate the variation of our site technique, can conveniently change travelling blower fan 50 number of rounds and the time of shutdown on producing.
Three-phase protective switch 20 is connected to three-phase ac contactor 30, and three-phase ac contactor 30 is used for connecting travelling blower fan 50.This three-phase ac contactor 30 is made up of secured core, dynamic iron core, spring, movable contact, stationary contact, coil, binding post and shell.Coil electricity, dynamic iron core action adhesive under electromagnetic force, drive movable contact action, make normally-closed contact separately, normally opened contact closes；Coil blackout, dynamic iron core drives movable contact to reset under the action of the spring.Three-phase ac contactor 30 in the present embodiment is used to connect and disjunction circuit, to reach to start and stop the purpose of travelling blower fan 50.
Controller 10 is connected to three-phase protective switch 20 and three-phase ac contactor 30 for controlling three-phase ac contactor 30 and the connection of three-phase protective switch 20 or disconnection.Controller 10 is connected to limit switch 40 for controlling the number of times that the travelling blower fan 50 of limit switch 40 detection moves back and forth.The lug of limit switch 40 has hat type cover screw.
In the present embodiment, limit switch 40 uses the small-sized limit switch 40 of TaiWan, China MOUJEN Mao Ren.Limit switch 40 feature is that plastic shell is lightweight, various different connecting rod can be coordinated, having lug tool hat type cover screw, limit switch 40 has adjustable, dust-proof, grease proofing, waterproof and double loop design, can reach the precise requirements of travelling blower fan 50 multiple-contact.
Controller 10 is connected to timing piece, and timing piece is connected to three-phase ac contactor 30 for the time calculating three-phase ac contactor 30 power-off.Timing piece is the time relay.
Shown in Figure 2, the present embodiment relate to a kind of travelling blower fan autocontrol method.A kind of travelling blower fan autocontrol method, comprises the steps:
It is passed through alternating current power supply so that controller 10 works.
Guan Bi three-phase protective switch 20 so that three-phase ac contactor 30 connects with three-phase protective switch 20 so that three-phase ac contactor 30 obtains electric so that travelling blower fan 50 works.
When travelling blower fan 50 moves at limit switch 40 and touches the contact of limit switch 40, limit switch 40 provides signal to controller 10.When limit switch 40 provides the signal of predetermined number to controller 10; controller 10 provides stopping signal to three-phase ac contactor 30; making three-phase ac contactor 30 with three-phase protective switch 20 disconnection so that three-phase ac contactor 30 dead electricity, travelling blower fan 50 quits work.
Timing piece calculates the time of three-phase ac contactor 30 dead electricity.When the time that timing piece calculates is equal to preset time value; controller 10 provides enabling signal to three-phase ac contactor 30; three-phase ac contactor 30 is connected with three-phase protective switch 20 so that three-phase ac contactor 30 obtains electric, and travelling blower fan 50 works on.
Circulate with this.
According to needs of production, when limit switch 40 provides the signal of 5-10 time to controller 10, controller 10 provides stopping signal to three-phase ac contactor 30.Preset time value is 10-15mi n.
The travelling blower fan autocontrol method that the present embodiment relates to; have employed three-phase ac contactor 30; when travelling blower fan 50 is opened; three-phase ac contactor 30 is closure state; after travelling blower fan 50 has walked up and down preset times, limit switch 40 counting presets secondary and one signal of input is to controller 10, after controller 10 internal processes calculates every time; export a stopping signal and disconnect three-phase ac contactor 30, so that travelling blower fan 50 stops.Travelling blower fan 50 it is again started up after starting timing 10 minutes; so circulation, thus reach travelling blower fan 50 and start and shut down alternately, travelling blower fan 50 autocontrol method that this utility model relates to; every day so that travelling blower fan 50 reduces by 1200 degree of electrical losses, to reach to save the purpose of the energy.
The travelling draught fan automatic control device that the present embodiment relates to, deft design, rational in infrastructure, practical reliably, improve automaticity.Being provided with three-phase protective switch 20, three-phase protective switch 20 has automatic protection circuit, and when circuit malfunctions or electric motor short circuit, three-phase protective switch 20 can automatically cut off power supply, prevents fault coverage from expanding.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, all it is considered to be the scope that this specification is recorded.
Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
